Description

Mandatory part

• Our objective is to code pipex that should be executed in this way:

./pipex file1 cmd1 cmd2 file2

• Execution of pipex should be similar to the next shell command:

< file1 cmd1 | cmd2 > file2

file1, file2 - filenames

cmd1, cmd2 - shell commands with their parameters

• Handling errors must be like in shell

Bonus part

• pipex should handle multiple pipes:

./pipex file1 cmd1 cmd2 cmd3 ... cmdn file2

is equivalent to next shell command:

< file1 cmd1 | cmd2 | cmd3 ... | cmdn > file2

• pipex should support « and » when the first parameter is here_doc:

./pipex here_doc LIMITER cmd1 cmd2 file

is equivalent to next shell command:

cmd1 << LIMITER | cmd2 >> file
